ide: add ->read_sff_dma_status method
Add ->read_sff_dma_status method for reading DMA Status register and use it instead of ->INB. While at it: * Use inb() directly in ns87415.c::ns87415_dma_end(). There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
